The debt entry said that shrink-wrapped leaves, which push later and pop in
balance, could be framed. They cannot as the framer works now: lowering RSP on
entry moves their later pushes onto the spills, which keep their addresses.

Match the AT_REMOVEDIR and rmdir sites so file reparse points stay on the old unlink path. Cover file symlink unlinkat on Windows and point the debt at the drive-target consumers.
rmdir followed the junction and reported ENOTEMPTY, and unlink treated it as a real directory, so a junction to a non-empty folder could not be removed.
Main's #9573 implements scePthreadResume right after the
scePthreadMutexattrSetkind stub this branch removes from libkernel_sys;
the merge takes main's scePthreadResume and leaves the stub out.
Main's public-header audit wants one header declaration per export, so
the merge declares this branch's scePthreadMutexattrSetkind,
scePthreadMutexattrGetkind and pthread_rwlockattr_settype_np in
libkernel's Api.hpp, drops their stub declarations from libkernel_sys's
Api.hpp, has Mutex.cpp take sceKernelError from libkernel's Api.hpp,
and has the test include the libkernel headers instead of its own
declarations.
The firmware disassembly (the real Sony libScePsml.sprx inside PPSA20397)
shows scePsmlMfsrInit returning 0x8A810012 before touching the initialized
flag when sceKernelIsTrinityMode is 0, so on the modelled console every MFSR
call correctly stays uninitialized instead of reaching the unimplemented
dispatch path. The shared-resources pair likewise returns 0x8A81000D for
disallowed types and 0x8A810015 while a shared-resources object already
exists.
Two stream send behaviours of XNU differ from FreeBSD and Linux:
- MSG_DONTWAIT does not keep a stream send on a blocking socket from
waiting for buffer space; XNU only skips the wait for the send buffer
lock. A 16 MiB send to a slow peer blocked until the peer went away.
A MSG_DONTWAIT transfer now also passes XNU's MSG_NBIO (0x20000), which
makes one call non-blocking: the send queues what fits and returns that
count, or EAGAIN when nothing fits.
- A blocking stream send that fails after queuing data, for example when
sceNetSocketAbort shuts the socket down, returns only the error, where
Linux returns the bytes queued. A blocking stream send now goes to the
host in sends of 64 KiB and reports the bytes of the sends that
completed when a later one fails, as #8658 does.
The debt entry records the undocumented flag and the bytes that a failing
64 KiB send queued but does not report.

sceNetEpollCreate fails with EINVAL for a null name or non-zero flags,
sceNetResolverCreate and sceNetGetMacAddress for non-zero flags, and
sceNetResolverStartNtoa, before any other check, for a negative timeout
or retry count or a flag bit outside 0x10001, as prosper reads the
libSceNet module. The two accepted resolver flag bits are still ignored,
which the debt file now records.
An image_store with DIM 2D_ARRAY through a 1D T# had no runtime image
mode, so the dispatch stopped with "image descriptor is incompatible
with the static runtime image interface". #2348 added a 1D mode for
DIM 2D stores only.
Write-only 2D-array storage images now get the same 1D mode as the 2D
case. On RDNA2 (gfx1036, hardware oracle) such a store writes texel x
and ignores y when the slice is 0, and writes nothing for any other
slice, with DEPTH 0 or 3, so the store is skipped unless the slice is 0.
New execution test agc_driver_image_store_line_through_plane_array.

The RDNA program decode sweeps linearly up to the last s_endpgm past the
furthest direct branch target, so it also decoded words that no path
reaches and threw on any it could not decode. A word directly after
s_branch, s_endpgm or s_code_end that fails to decode is now skipped;
the decode still throws that word's error when a direct branch or
s_call_b64 targets it, and a failure on a word reachable by fall-through
is unchanged. The control-flow graph starts the block after s_branch and
s_endpgm at the next decoded instruction instead of the next word.

On PS5 firmware 13.60 sceRtcSetTime_t(NULL, -1) returns
SCE_RTC_ERROR_INVALID_VALUE and sceRtcSetTime_t(NULL, 0)
SCE_RTC_ERROR_INVALID_POINTER: negative seconds are rejected before a
null destination under the later SDK rules. The other measured
GetDayOfWeek, SetTime_t and FormatRFC3339 results already matched.
